The profile on the Beersmith forum is for the 20l.. I am using the short maltpipe (25l) in the 50l BM.

I have modified the above profile more1. I have measured my hourly boil off (I boil at 102 degrees, my bm has a lagging jacket, also i have the dome lid). My new value is 5l per hour.2. I have changed the mash tun weight to 14kg
